Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery Detected by Echocardiography in an Asymptomatic Young Athlete.

The anomalous origin of the coronary artery from the pulmonary artery (ALCAPA) is the most common congenital coronary artery anomaly. Up to 90% of patients die during the first year of life. It is unusual for an ALCAPA patient to survive to adulthood. We present a case of an asymptomatic young athlete with ALCAPA, in which the diagnosis was established by echocardiography during pre-participation physical evaluation. The patient underwent surgical closure of the left main coronary artery ostium through the inside of the main pulmonary artery and coronary artery bypass grafting. He was discharged after 6 days and remained well during follow-up visits. We emphasize the importance of echocardiographic examination during pre-participation cardiovascular screening in young athletic populations to avoid sudden death related to ALCAPA.
